Roast Sugar-Sprinkled Peaches

This is scarcely a recipe: get 5–6 peaches (enough for 2 halves each and then a little more), split them in half, remove the stones and put them, cut-side up, in a buttered ovenproof dish in which they fit snugly. Into each cavity add a dot of butter and a tablespoon of sugar – vanilla, brown or ordinary white as you like – then another few dots of butter and roast in a preheated gas mark
